Uji Efektifitas Herbisida Atrazin, Mesotrion, Dan Campuran Atrazin+Mesotrion Terhadap Beberapa Jenis Gulma

The aimed of this research was to know the effectiveness of mixing herbicides with active ingredient atrazin and mesotrion in controlling weeds and know the mixture characteristic. This research conducted in the plastic garden house private in Natar, South Lampung and in the Weeds laboratory of Agriculture faculty, Lampung University from June until July 2013. This Research arranged in a Randomized Completely Design (RCD). Treatment consists of three types of herbicides with six level of dosage active ingredient, namely of single herbicides is atrazin 500 g l-1 (0, 76, 152, 304, 608, and 1.215 ha g-1), mesotrion 50 g l-1 (0, 11, 22, 43, 86, and 172 g ha-1), and mixed herbicides from atrazin 500 g l-1 + mesotrion 50 g l-1 (0, 28, 56, 112, 225, and 450 g ha-1). The target weed were a type of broadleaves (Asystasia gangetica), a type of grasses (Paspalum conjugatum), and a type of sedges (Cyperus kyllingia).Homogenity tested using Bartlet and aditivity tested using Tukey, data analyzed by Analisis of Variance and different median values tested with Least Significant Difference (LSD) level 5%. Results showed that an active ingredient mixture of atrazin 500 g L-1 + mesotrion 50 g L-1 has LD50 expectation value of 51,48 g ha-1 and LD50 treatment of 257,48 g ha-1 with the co-toxicity value was 0.2 (co-toxicity < 1) until mixture was antagonist

Efikasi Herbisida Amonium Glufosinatt Gulma Umum Pada Perkebunan Karet yang Menghasilkan [Hevea Brasiliensis (Muell.) Arg]

This research was aimed to determine the efficacy of glufosinate ammonium on weed in rubber plants and to know it composition change. Research was conducted in the PTPN 7 UU Way Galih, Tanjung Bintang, and Weed Laboratory, Agricultural Faculty, University of Lampung, during June – August 2013. The Research using randomized complete block design with 6 treatments(t1= 225 g ha-1; t2= 300 g ha-1; t3= 375 g ha-1; t4= 450 g ha-1; t5= mechanical control; t6= control/ no treatment) and 4 replications. Data obtained were analyzed using analysis of variant. Homogenity using Bartlet Tast and aditifity using Tuckey Test. Differences in median tested using Least Significant Differenc (LSD) level 5%.Results: (1) all treatments of ammonium glufosinate (225 – 450 gha-1) significantly reduced weed total, broad leaves, and Selaginella wildenowii for 12 Weeks After Aplication (WAA). (2) Ottochloa nodosa and Grasses can be controlled only in higest dosage level of ammonium glufosinat (450 g ha-1) at 4 WAA. (3) Cyrtococcum acrescens can’t be controlled by treatments of ammonium glufosinate herbicide (225 – 450 g ha-1). Keywords : Ammonium glufosinate, weed, Hevea brasiliensis
